Lin Chuan became cautious, and the aura wrapped in the wooden box and leaned over, although the flame had turned golden, but with the strength of Lin Chuan's divine sense, there was not much of a problem.

The golden flame was separated by the aura, and the black wooden box reached the top of the fairy spirit crystal, only to hear the 'click', the black wooden box had been crushed by Lin Chuan.

A purple-black powder was sprinkled from the wooden box, which looked inconspicuous, and the aura carefully controlled the purple-black powder to attach to the surface of the fairy crystal.

After about half an hour, all the powder adhered to the surface of the fairy spirit crystal, and at this time, Lin Chuan collected the aura that blocked the golden flames.

The golden flames on the periphery rolled in, instantly enveloping the fairy spirit crystal.

Snort ......!

A piercing sound suddenly sounded, and the golden flame that wrapped the fairy spirit crystal suddenly soared, instantly turning into a huge wave of golden fire and sweeping out in all directions.

"Not good!" Lin Chuan secretly said in his heart that it was not good, and his divine sense retreated quickly, but the next moment, the golden flames that rolled wildly collided with Lin Chuan's divine consciousness.

Yes......!

Lin Chuan screamed, only to feel that his soul was burned, that kind of pain far exceeded the physical injury, this kind of pain Lin Chuan encountered for the first time.

"Young Master, hurry up and withdraw your divine sense!" Xiao Yin shouted anxiously on the side

Lin Chuan gritted his teeth, endured the severe pain, and took back the divine consciousness in the Heaven and Earth Oven, but the burning pain had not disappeared.

"What is this, it's too terrifying" After the divine consciousness returned, Lin Chuan still felt a little palpitation, that kind of pain is definitely not something ordinary people can bear.

"This is the catalyst that catalyzes the melting of the fairy crystal, it can instantly increase the power of the flame to a terrifying level, although the young master's divine sense is stronger than that of a cultivator of the same level, but it is no match for the flame that has been enhanced so many times" Xiao Yin explained

"Is there no problem now?" asked Lin Chuan

"Well, just wait for Gengjin and Immortal Spirit Crystals to be refined, but you don't need so many Immortal Spirit Crystals to cast a sword fetus, and the remaining young master can take some to refine magic weapons," Xiao Yin said

"Well, Xiaoyin, you watch for me, I'm concentrating on urging the Heaven and Earth Oven" Then Lin Chuan focused his attention and stared at the Heaven and Earth Oven, his hands pinching the trick continuously.

On the side, Xiaoyin paid close attention to the situation in the oven of heaven and earth, and when it was time to add materials, he would remind Lin Chuan, so that the cooperation between the two was quite skilled.

In this way, another ten days have passed, and the Gengjin and Immortal Spirit Crystals in the Heaven and Earth Oven have turned into two liquids, both of which are dark golden, slightly different.

Under Xiaoyin's reminder, Lin Chuan separated a part of the fairy spirit crystal, carefully fused it with the mass of heptyl gold liquid, and turned into a new liquid.

"Add psychic powder" Xiaoyin's voice came out.

Without saying a word, Lin Chuan separated a stream of aura, rolled up a box placed not far away and flew towards the Heaven and Earth Oven, and easily integrated the white powder in the box into the liquid.

"Join the Ten Thousand Spirit Stones" Xiao Yin's voice came again.

Lin Chuan did not hesitate to put the Ten Thousand Spirit Stone into the Heaven and Earth Oven.

......

In this way, with the help of Xiaoyin, more and more heavenly treasures were put into the heaven and earth oven by Lin Chuan and integrated into that mass of liquid.

The liquid that used to be a dull golden color has been transformed into a variety of colors by incorporating countless precious materials, and it is surrounded by a bright light, making it look very beautiful.

At this point, the mass of liquid was the size of a human head, and occasionally stretched and contracted around it, as if it had life.

"Start joining the essence blood refining!" Xiao Yin's voice came into Lin Chuan's ears again.

I saw Lin Chuan open his mouth, bite the tip of his tongue, and a bloody sword burst out, wrapped in spiritual energy and flew into the heaven and earth oven, and instantly came to the side of the liquid.

First use the aura to separate the flames around the liquid, and then pour the blood on the liquid, the scarlet blood just touched the liquid, and instantly emitted a 'poof' sound.

But soon all the blood was integrated into the liquid, making the colorful liquid begin to emit a faint blood glow, which felt a little weird.

"Now every two hours, the young master must integrate his essence and blood into the materials, so that after three days and three nights, he can become a complete success," Xiao Yin said

"No problem" A determined look flashed in Lin Chuan's eyes, in order to forge a sword fetus, he did not hesitate to do so, Xiao Yin's understanding of the Refining Dao was still above Lin Chuan, so Lin Chuan did not have any doubts about Xiao Yin's words.

Then Lin Chuan released some essence blood every two hours, and used the aura to wrap it into the heaven and earth oven, so that after three days and three nights, Lin Chuan lost a lot of essence blood, and his face couldn't help but become a little pale, but his hands still did not stop pinching.

Xiao Yin watched from the side, and couldn't help but be a little worried.

"No problem, don't worry" Lin Chuan saw Xiaoyin's worry, smiled slightly, and said casually.

"Well, it's okay, this step has been completed, and then the young master can increase the power of the flame and start the extreme forging!" Although Xiao Yin was worried, it had reached this point, and it was impossible for her to let Lin Chuan stop, so she had to continue to follow the casting steps of the sword fetus.

Hearing Xiao Yin's words, a glimmer of light flashed in Lin Chuan's eyes, and a spiritual aura flew out, rolling a jade bottle a foot high not far away, and a dark black liquid flew up from the jade bottle, condensing into a liquid ball the size of a watermelon in the air.

Then he was wrapped by Lin Chuan's aura and put into the Heaven and Earth Oven, and the next moment, there was a black sphere in the internal space of the Heaven and Earth Oven.

Lin Chuan poured spiritual power into the liquid, and suddenly shouted: "Explosion!"

Bang!

The black sphere exploded instantly, turning into black mist and sweeping out, and after the surrounding flames touched these black mists, they instantly burned violently.

Thundered!

Endless flames were running wildly in the oven of heaven and earth, as if they were going crazy, rolling up endless waves of fire, such a situation, Lin Chuan seemed to have expected it a long time ago.

The speed of the two hands in front of him instantly accelerated, and the flames in the Heaven and Earth Oven contracted violently, turning into a huge mass that enveloped the liquid in it, and began a crazy calcination.

Snort!

The surface of the colorful liquid boiled, bubbles emerged, bursting at the same time making a harsh sound, and at the same time, wisps of black gas rose, escaping from the liquid, and were swept up by the surrounding flames, disappearing in an instant, this liquid was so calcined, and the volume was rapidly reduced.

At this time, the power of the flames around the liquid reached an astonishing level, if it was an ordinary refining furnace, I am afraid that it would be incinerated by that flame in an instant, fortunately, this heaven and earth oven can withstand such a terrifying flame.
